Stopping Sound

I seem to get this spammed into my console in bursts. My friend seems to think it is a developer comment. It is also in yellow if that means anything. Could anybody tell me what sort of script would use this? Thanks guys.

What do you mean spammed into console in bursts? If you want to stop sounds, type stopsound in console

No, I mean that this exact message is getting spammed into console: “Stopping sound”

A clientside script (which could be in any of your addons either manually installed or on workshop) on the server is printing that text to the console.
